Answer:

Table A and Graph A

Step-by-step explanation:

See the attached tables and graphs.

Table A gives the ordered pairs (1,2), (2,4) and (3,6).

Take the first two pairs of points.

The equation of the straight line passing through those points will be

$\frac{y - 4}{4 - 2} = \frac{x - 2}{2 - 1}$

⇒ y = 2x

Therefore, the table A represents the equation y= 2x.

Now, as shown in graph A, the points (0,0) and (1,2) and (2,4) through which this equation of straight line passes.

Therefore, the equation y = 2x is represented by graph A.

Hence, Table A and Graph A are the answers.

Required information Section 01.02 Exercise 14 - Effects of changing data values on mean, median, and standard deviation There a

Nutka1998 [239]

Answer:

Mean will Increase .
Median remains unchanged.
Standard deviation will increase.

Step-by-step explanation:

We are given that there are 14 employees in a particular division of a company and their salaries have a mean of $70,000, a median of $55,000, and a standard deviation of $20,000.

And also the largest number on the list is $100,000 but By accident, this number is changed to $1,000,000.

Now we have to analyse the Effect of this change in data values on mean, median, and standard deviation.

Mean will get affected because $1,000,000 is a very huge value as compared to $100,000 and is considered to be an outlier and we know that mean is affected by outliers as mean will change to $134285.7143 after replacing $100,000 with $1,000,000 .
Median will not get affected as median the middle most value in the data set and since $1,000,000 is considered to be an outlier so median remain unchanged at $55,000 .
Standard Deviation will also get affected as due to outlier value in the data set the numerator value will increase very much and due to which standard deviation will also increase.

I NEED HELP ASAP!!!!!! I WILL GIVE PRAILIEST TO THE CORRECT ANSWER

Norma-Jean [14]

-13 (q + 4) = 7q + 16

I think to solve it you do this first:

-13q + -52 = 7q + 16

And then I think you do:

-6q + -36

And thats all I can remember sorry ):

That -6q + -36 might be the answer I think (:

Hope I could help (:

A salesperson earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns $4,800

madam [21]

4800 divide by 3=1600 (2 cars 1 truck)

4600-1600-3000 (6 cars)

3000 divide by 3 = 1000(2cars)

1000 times 2=2000(4 cars )

4800-2000-2800 (2 cars 3 trucks)

$2,800 is your answer

Morgarella [4.7K]

Water = 5 bottles * $0.90 = $4.50
meat = 8 pounds * x amount.

Total = water + meat prices = $26.90
26.90 = $4.50 + 8x
22.40 = 8x
2.8 = x

The price per pound of meat is $2.80.
